Satellite Buses
A spacecraft bus is the common platform a satellite is built on, the structure, power, and propulsion that different payloads share. Grouping the catalog by bus shows how many objects fly on each platform. Open any bus for its typical specifications, launch history, and the full satellite list.
KeepTrack groups satellites across 1,546 distinct spacecraft buses. 613 of them carry three or more objects and have their own page.
Data current as of 2026-07-20.
